Summary

A no-power calcium-chloride desiccant bag for closets, laundry rooms and other small enclosed spaces, with a hook to hang it and a clear chamber for the brine it collects. Check before buying: it is disposable rather than refillable, and the listing can point at a different-size bag than the one you expect.

Strengths

  • Runs without electricity or batteries, so it works in closets, boats and RVs where a dehumidifier cannot go.
  • Removes real moisture: in CHOICE’s sealed test it cut humidity to 43% within three days.
  • A hook and a clear brine chamber make it easy to hang and check.
  • Grocery pricing of about $4–$5 a bag makes it a cheap way to test a damp spot.
  • Owners in boats, RVs and basements report it handles small moisture problems.
  • No maintenance beyond watching the crystals dissolve.

Weaknesses

  • It is slow: CHOICE measured about 2 ml of water per hour against 113–388 ml/hour for electric dehumidifiers.
  • It is disposable and cannot be refilled.
  • Effectiveness drops in well-ventilated rooms.
  • The collected brine can damage leather and metal.
  • One owner in humid Florida reported mold growing on the crystals with no water collected.
  • Listing sizes are muddled: the ASIN can point at 16 oz bags while the product is 15.4 oz.

What it can and cannot do

CHOICE’s 2025 test put a container in a sealed closet-size chamber at 80% relative humidity with a fan. Within three days it pulled humidity down to 43% and collected almost half a cup of water. At 65% humidity it removed about 2 ml of water per hour on average, against 113 ml/hour for the worst electric dehumidifier in the same test and 388 ml/hour for the best. That is the honest picture: it works on low-level damp in a closed space, and it is nowhere near an electric dehumidifier for anything bigger.

Running costs and where to put it

Kroger lists the 15.4 oz bag at about $4.89, and Lowe’s lists a 46.2-oz three-pack at $12.48, roughly $4.16 a bag. There is no power draw and no refill; when the crystals are gone the bag goes in the trash. A label caution worth repeating: it works in closed areas and its effectiveness is compromised in well-ventilated spaces, so it is wrong for an open room. Do not use it in a moving vehicle, do not hang it near leather, and keep the brine away from leather and metal.

Which model this is

This page covers the DampRid Fresh Scent hanging moisture absorber in the 15.4 oz bag, product code FG83FSSB, made by W. M. Barr & Co. of Memphis. The same line also comes Fragrance Free, Lavender Vanilla and Pure Linen. The listing ASIN is B09QXW1DHK, which some sellers pair with 16 oz bags (code FG86FSSBAM) even though those claim 14% more absorbing power than the 15.4 oz bag’s 10%. Verify the bag weight on the page before ordering.
